7095 * dmae-operations (writing to pram for example.)
7096 * note: can be done for only function 6,7 but cleaner this
7098 * b. Write zero+valid to the entire ILT.
7099 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
7100 * VNIC3 (of that port). The range allocated will be the
7101 * entire ILT. This is needed to prevent ILT range error.
7102 * 2. Any PF driver load flow:
7103 * a. ILT update with the physical addresses of the allocated
7105 * b. Wait 20msec. - note that this timeout is needed to make
7106 * sure there are no requests in one of the PXP internal
7107 * queues with "old" ILT addresses.
7108 * c. PF enable in the PGLC.
7109 * d. Clear the was_error of the PF in the PGLC. (could have
7110 * occurred while driver was down)
7111 * e. PF enable in the CFC (WEAK + STRONG)
7112 * f. Timers scan enable
7113 * 3. PF driver unload flow:
7114 * a. Clear the Timers scan_en.
7115 * b. Polling for scan_on=0 for that PF.
7116 * c. Clear the PF enable bit in the PXP.
7117 * d. Clear the PF enable in the CFC (WEAK + STRONG)
7118 * e. Write zero+valid to all ILT entries (The valid bit must
7120 * f. If this is VNIC 3 of a port then also init
7121 * first_timers_ilt_entry to zero and last_timers_ilt_entry
7122 * to the last entry in the ILT.

7131 * Step 2.d can be done only for PF6/7 and the driver can also check if
7132 * there is error before clearing it. But the flow above is simpler and
7134 * All ILT entries are written by zero+valid and not just PF6/7
